I have this weird problem that Firefox does not open a perfectly normal select box (see code below). I've already tried to disable all the plugins, themes etc, but still it won't open them. Is there probably some strange setting that causes this?

      <option value="0">aaaaaaaaaaa</option>
      <option value="1">bbbbbbbbbbbbb</option>
      <option value="2">cccccccccccc</option>
      <option value="3">dddddddddddd</option>

    Any other sites that are giving you trouble? Which OS and which Firefox? (The above jsbin.com/equtu works fine in Firefox 3.6 on Mac OS X.) – Arjan Feb 2 '10 at 12:00

Just in case this is caused by an extension or by something odd in your profile: try running firefox without any extensions, and with a fresh (empty) profile:

firefox -safe-mode -P new_profile_name

and see if you can reproduce the problem.


Sometimes Firefox doesn't like select boxes not in a form. Put tags around your select box.

  • sorry - meant "put FORM tags around..." – gaje Aug 27 '10 at 20:01
